‘Step 5: It will return 2 tables if the isbn number is correct so below is the logic to get book detail
If ds Is Nothing = False AndAlso ds.Tables(1).Rows.Count() > 0 Then
Me.lblBookName.Text = ds.Tables(1).Rows(0)(“title”).ToString()
Me.lblAuthor.Text = ds.Tables(1).Rows(0)(“author”).ToString()
Me.lblPublisher.Text = ds.Tables(1).Rows(0)(“publisher”).ToString()
Else
Me.lblMessage.Text = “Sorry ISBN Number not found, Please try different number.”
End If
Else
Me.lblMessage.Text = “Please enter the ISBN number”
End If

So in this way we get the book detail from ISBN using WorldCat.org provider.

Dear Friends,
I am explaining basic steps by which you can get book detail from ISBN using ASP.NET

I am using 3 providers which have this database catalog and provide such facility.
So below is the list
1) isbndb.com
2) worldcat.org
3) Google book API
So let us start with ISBNDB.com first. So to use this service you have to create first access key.
